Thanks for that information! I will look at xtar...
I think this solution is working well:
1) For initial bulk backups, I mount a volume on my Linux server via
NFS or SAMBA. Then I use "ditto --rsrc" to move the data over. That
way, the NFS/SAMBA client on the Mac side takes care of filename
mappings and resource forks.
I tried to pipe ditto output through ssh as shown in the ditto man
page, but for 100 GB transfers this was too fragile. Actually any net
connection when moving 100 GB is fraught: sometimes I use external hard
disks to save the data from the Macintosh onto EXT2 partitions as pax
archives.
(If you have a developer release of 10.4.x, ditto has an additional
option to prevent out-of-memory errors for large transfers:
"--nocache")
2) For subsequent incremental backups, rsync+hfsmode tunneled through
ssh.
My "ultimate" solution would probably be to patch resource-fork support
into the "star" (ess-tar) program; star strives for full POSIX
compliance, and is the *only* tar/pax/cpio program that I have run
across that does not choke on weird file names or very large files.
I use star on my FreeBSD and Linux servers for full and incremental
system dumps and the archives are totally portable across different OS
types and system architectures.
